Disappearing Foreign Keys in phpMyAdmin

Question

I am creating a new table inside mysql and I am trying to add a foreign key constraint to one of the fields.

CREATE TABLE `onlineorder` (
  `receiptid` varchar(10) NO         


        

Answer 1

Also, PHPMyAdmin removes extracts any CONSTRAINTS until after all the tables have been created and the data has been inserted. If you use as PHPMySql to dump the table for you, you'll find at the end of the file an UPDATE table section with all your ADD CONSTRAINT entries.
